Old Novae: When New Becomes Old*

Despite their brightness at maximum, classical novae are very faint at minimum light implying little or no follow up at all during quiescence. In fact, about 3/4 of the 204 novae that erupted before 1980 still lack spectroscopic observations or even an unambiguous identification of the post-nova. We embarked on a project aimed at deriving the physical properties of old novae decades after the explosion thus placing post-novae in the framework of CV-evolution and being able to compare the characteristics of the eruption with the characteristics of the remnant. We present an...

The GTC/OSIRIS Data Reduction system

We present the online and the offline data reduction system for OSIRIS,
theoptical multi-mode instrument for Grantecan. The software is written
in Pythonand invokes IRAF tasks which have been optimized for the
instrument. Theflexibility of the software makes it easy to be adapted
to othertelescopes/instruments.
